Application filed November 11, 1915.

To all w iwm it may concern:

Be it known that 1, JAMES l). SMITH, a

production of an automobile wheel rimv which will reduce thetime required by the rims now in use to secure the tire on a rim and the rim on the folly.

In the accompanying drawings l: have illustrated one complete example oi"? the physical embodiment of my invention eon-- structed according to the best mode it have so far devised tor the practical application of the principles of my invention.

Figure i represents a side view in elevation of a portion of an automobile wheel equipped with my invention.

Fig. 2 represents a view similar to Fig. l. oi the opposite side of an automobile wheel.

Fig"; 3 represents a transverse sectional view taken on line 3-3 of Fig. l. i

Fig". 4 represents a transverse sectional view taken on line H of Fig. l.

Figs 5 and 6 represent detail views of the novel pivoted clamping member employed in my invention, and 7 Figs. 'Z, 8 and 9 represent detail views of the novel locking key member used in combination with the clamping member.

My invention relates to that particular class of Wheels embracing pneumatic'tires wherein thelatter are of the Well known clencher or of similar standard type and wherein is employed a mechanical contriv ance securing and releasing the tires to and from the rim.

As will hereinafter appear, it provide by my invention a simple and secure means for secursly clamping the tire and rim upon the wheel, the said means bei11g*so con street-ed as to permit of ready removal for repair or other purposes.

The letter J designates an ordinary substantially constructed Wooden wheel having Speoification of Letters Patent.

Patented Jan 2 2, this,

Serial No. 60,911.

the telly D of the usual construction on one side of which is secnred'by means of fastenings G, the fixed tire engaging plate P, to which is removably secured the ring plate C, the purpose of which will be hereinafter described.

Secured in the telly at spaced intervals are the casings 0. having each a head cl for retaining a collar 0 in its proper position on a bolt 1) which engages the threaded opening in a locking key a, said threaded opening being parallel with the walls of i the casing c and said key a being diagonally disposed in the casing and engaging an opening in the ring plate O, locking the pivoted clamp 7' in position as will be hereinafter set forth.

The pivoted clamp f, is alsosecured in. the telly in the casing e, by fastening w, and is pivoted in. said casing by the pivot g, and has one end reduced and threaded and en-- gaging an opening in the ring plate C,

upon which end is the nut h, for binding the clamp in locked position as hereinafter stated. The other end of the clamp f, is formed with a lip or hook which passes through. an opening or slot in the removable plate l3, and is adapted to engage and retain said plate in position.

The flanges of the tire it will be understood are engaged by the plates B and P and to secure the tire in place the plates B and l? are adjusted to fit upon-the flanges and in position having" the proper slots registering with the clamps 7, next turn the plate B around so that the plate will slip under the hook or lip f of the clamp, when the belt or bolts- 5 are unscrewed forcing the keys 0!- outwardiy locking the clamps in locked position through the diagonal slant of the keys a tendingto turn the ring plate C around. the wheel thus causing the clamps to bind more tightly the removable plate B, when the nuts h are tightened to further loch: the clamps.

ins will be readily seen, should the nuts it become loose, theheys a will prevent the .clarnps 7' from becoming unlocked.

Having; thus described my invention,

Wheel, a ring plate next to the fixed plate, said pivoted clamps engaging .said ring plate and removable plate, and locking keys for preventing the pivoted clamps from disengaging the removable plate, substantially as described.

2. In an automobile Wheel, the combination with a removable plate, of pivoted clamp members mounted in casings secured at intervals-in the felly of said wheel, said clamp vmembers being so arranged as to clamp the removable plate to the Wheel, and locking members for preventing the pivoted clamp members from disengaging the removable plate, all as described.

In this invention all claims are set for the purpose specified.
